WebThe size of Cr⁶⁺ ion carries 6 positive charges and is very small because 18 electrons are attracted by 24 nuclear charges. Therefore, the charge density (i.e. charge : volume ratio) of Cr⁶⁺ ion is very high. This leads to a very high polarizing power of Cr⁶⁺ ion, and the electron clouds of the surrounding anions are drawn back to the Cr⁶⁺ ion. WebWe start with a single hydrogen atom (atomic number 1), which consists of one proton and one electron. Referring to Figure 6.26 or Figure 6.27, we would expect to find the electron in the 1 s orbital. By convention, the m s = + 1 2 value is usually filled first.
